Photon emission from a segmented ion-trap – cavity system: simulation and implementation — •Stephan Kucera, Max Bergerhoff, and Jürgen Eschner — Universität des Saarlandes, Experimentalphysik, 66123 Saarbrücken

Atom-photon interfaces [1,2] are basic requirements for quantum networks with single trapped ions. The efficiency of such interfaces has been shown to increase significantly by the use of resonators [3]. Following this direction, we are developing a new segmented ion trap for ⁴⁰Ca⁺ ions with an integrated fiber cavity [4,5] envisaging the implementation of a high-rate and high-purity quantum repeater cell (QR-cell) according to [6,7] on the basis of single-photon emission.
